Chimney inspections pass or fail, nothing in-between – gas zombies black ops


Having a rip-roaring open-flame wood fire in your living room gas vs electric stove safety is serious business. According to the Consumer Product Safety Commission (CPSC), an estimated 22,300 residential structure fires occurred in homes every year from 2012 to 2014 as a result of a Fireplace, Chimney, or Chimney Connector fire. That’s absolutely crazy. The Chimney Safety Institute of America (CSIA) has this information published on its website. We’re serious about chimney safety

Structure Tech began offering level 2 chimney inspections as an add-on service to our home inspections approximately two years ago. We initially partnered up with a chimney inspection and repair company to provide these inspections, but we’ve since converted this to an ‘in-house’ service. Our very own Patrick Brennan moved from home inspector to full-time gas prices going up 2016 chimney inspector after obtaining his Certified Chimney Sweep designation by the Chimney Safety Institute of America ( CSIA).

Since we began offering chimney inspections, I’ve become convinced that most wood burning masonry fireplace chimneys have problems. The problems are so widespread and so serious that electricity usage in the us the National Fire Protection Association (NFPA) recommends a level 2 chimney inspection anytime there is a sale or transfer of a property. Where the level 2 inspection recommendation comes from

While NFPA 211 is not law or code, it is generally accepted as the appropriate level of safety and care for construction and inspection of fireplaces. Not only that, but this document is also referenced repeatedly by the International Residential Code, as well as the Minnesota Mechanical and Fuel Gas Codes. For example, if you turn to the Minnesota Fuel gas dryer vs electric dryer calculator Gas Code for directions on how to construct a metal chimney, section 503.5.2 says Metal chimneys shall be built and installed in accordance with NFPA 211. You’ll find many such references in the model codes.

If the flue liner in a chimney has softened, cracked, or otherwise deteriorated so that it no longer has gas x reviews ratings the continued ability to contain the products of combustion (i.e., heat, moisture, creosote, and flue gases), the liner shall be either removed and replaced, repaired, or relined with a listed liner system or other approved material that will resist corrosion, softening, or cracking from flue gases at temperatures appropriate to the class of chimney service.

Side note: there are plenty of chimney companies here in the Twin Cities who are happy to pass all sorts of nasty 3 main gas laws chimneys without even using an inspection camera. They pencil-whip safe chimney reports, and people who want these reports keep the business flowing. I’ve blogged about these chimney hacks before, and frankly, the whole topic disgusts me. But do these small gaps really matter?

Yes, these small gaps make a difference. They can allow heat from the flue liner to get transferred to the bricks. Then bricks can then transfer that heat to the wood structure. When that happens, the wood goes through a process gas and sand called Pyrolysis, wherein the ignition point of the wood drops significantly. This happens over a long period of time, and can eventually lead to a structure fire.
